I would be happy to help you! In order to install the SMI Air Force One Supplemental Braking System item # SM99243 on your 2022 Newmar Dutchstar with toad vehicle fitting all you will need is the SMI Second Vehicle Kit for Air Force One Supplemental Braking Systems item # SM99209 and the SMI Air Force One Coiled Air Jumper Kit for Spartan Chassis item # SM6296. The Air Force One Tank Assembly should already be installed if you have the airbrake connector.

You will also want to use the Roadmaster Brake-Lite Relay Kit item # RM-88400. This relay is required to prevent your Ranger's brake signal from overriding the turn signal from the RV when applying the brakes during a turn.

Since you already have the Blue Ox Ascent Non-Binding Tow Bar # BX4370 you will need the following parts to flat tow your Ranger:

Base Plate Kit: Blue Ox Base Plate Kit # BLU77XR

Wiring Kit: Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit item # RM-15267

I have linked a couple of installation videos below.
